Question about Dishwashers

1 Answer

Figidare dishwasher Upper arm not rotating, no water coming from top hole to fill upper arm.Lower arm rotates shoot water up cleaned filter screens. Check ball seems ok by pump, is there a location it (ck ball) should be? My upper arm is not rotating, things are coming out crusty, and it's definitely not getting water to the upper arm. My check ball seems to be plugging the tube the water goes up in.

It seems other posts were correct - The upper arm doesn't spin all the time. Once I learned that, and let the dishwasher cycle through, I saw that the upper arm does spin. So, there wasn't a problem with the upper arm afterall. That doesn't solve my crusty dishes problem, but that may have something to do with the soap we're using. We're going to try changing that next.

I have an LG model LDS4821 dishwasher that quit washing clean. Top rack is the dirtiest. Water is hot and bottom drain is clean.


The most likely cause is a blocked or clogged wash arm. Many times when the wash stops the debris blocking the spray will back away. The holes in the arm are aimed to cause the arm to rotate. The clogged hole is usually an outer diameter hole which provides the force for the arm to rotate.

Some upper end washers have a blocked arm sense to alert when arm is blocked.

Careful not to deform the geometry of the hole when removing the debris. Tweezers work the best.

Dishes are cloudy and have soap residue. Have cleaned upper &lower spray arm often, as good as posible (find holes plugged). water level & temp. seems normal . Water intake screen appears clean


Clean the spray arm jet holes if they are blocked. Check whether you have filled the rinse-aid dispenser.

Check whether arm turns freely when rotated by hand manually.

Top sprayer not working


Check and clean the filter inside at the bottom of the dishwasher. Make sure the spray arm rotates freely and that the holes are not clogged. If the dishwasher has a collapsable tower to shoot water into the upper spray arm, make sure it is not stuck and that nothing is blocking it from rising.

Will not clean dishes on the upper rack


Make sure you get water to the dishwasher. Check to see if the water shut-off valve (located under the sink) is open. If you get water to the dishwasher, but there is still no water inside during the fill cycle, the problem might be with a faulty water valve (located at the bottom of the dishwasher, behind the kick panel, on either side), in which case replace the water valve.

If there is not enough water, the dishes would not get cleaned. This could be caused by a partially closed water shut-off valve (located under the sink), or a faulty dishwasher water valve (located at the bottom of the dishwasher, behind the kick panel, on either side).

There is usually two, sometimes three spray arms in a dishwasher. Make sure there is no debris blocking the holes inside each spray arm.

LG LDS5811WW Low pressure out of spray arms


On the LG LDF xxxx dishwasher family, the Vario feature uses a motor/check valve to switch between "full power" cleaning from _either_ the lower or the upper spray arms, never at the same time. So, not seeing the upper arm spin during the lower arm spinning is standard operating procedure.

But back to your problem. Step one would be to remove the filter assembly again and make certain that there is nothing (debris, broken glass) blocking the white areas where the check valve rotates to switch between upper/lower spray arms. A blockage there ~could~ cause impotent spraying/cleaning.

If there is no blockage and the impeller remains in good shape, suspect a failing wash pump motor. Try to isolate the noise to that motor.

Watch for error codes on the display and report back what you find, OK?

Good Luck!

Not enough water pressure to move upper arms or clean dishes


Recommend you pull the bottom spray arm straight up, then out of the DW.
Remove 9 phillips screws that hold the filter shroud down. Remove the filter and clean/rinse it out.
While the filter it out, grab a flashlight and inspect all over the sump area. Especilly in the area the has the check valve that rotates (Vario motor-driven) to feed the water pressure either to the lower and then the upper arms. Watch out for broken glass! Also, inspect the impeller to see if it is undamaged and spins easily.
Reassemble, then test out.
If problems remain, the the wash pump motor is probably the culprit. Do you get any error messages on the time display?
Good Luck!

Upper spray arm is not turning round even though water is coming through. We have checked the internal system for blockages and the machine is filling / draining as normal. When a full programme is run,...


I found the problem to be neither blockages of the upper arm or roof spray arm or the upper basket arm hitting the the back of the dishwasher. the problem was that the pump inlet where the food scraps are macerated was blocked with all manner of gunge including small chicken bones plastic and other detritus. Removal of the macerator housing under the upper filter housing using 2 different sizes of torx driver easily fixed the problem. Probably why the upper dish rack cleaning degraded overtime, Directly proportional to the amount of detritus blocking the intake screen behind the macerator.17a8801.jpgb9e8fa8.jpg789f2b8.jpgfb7a626.jpgator.

Lower arm won't spin


the arm only rotates with water shooting out of the angled jets at the end of the arm and these are probably blocked ( i assume it is free to totate manually) take the arm out and run water into the centre hole and this will help push whatever is blocking it to a visible position - usually rice or sweetcorn. you say there are no obstructions in arm but when no water flowing, the blockage tends to slump back into the main body of the arm and out of sight
